After several years of almost flawless performance, my HomeKit setup became unpleasant. I'm looking for some information before I delete the whole system and start from scratch.

In my kitchen I have a Hue Light strip under our cabinets as primary lighting and it is the oldest that requires a hub. I have two other Hue bulbs starting from the same hub. I have a few iDevices switches (running lamps, without hub) and a few Lutron wall switches (running outdoor luminaires, with hub). I also have an IKEA hub, but at the moment only the Sonos remote control works (more to come). AppleTV is our HomeKit hub.

At 5 in the morning, the kitchen lights turn on at 15%. When we enter the kitchen, we have to say to our HomePod, "Kitchen lights, 100%". It has also become our command to "turn on the kitchen lights" because, if they were in any other condition when they were turned off (say, dark), they would light up backwards if you just say "turn on the kitchen lights". . It worked for a few years.

Starting last week or so, whenever we say "Kitchen lights, 100%", literally, everything in the system starts simultaneously. If you say "turn on the kitchen lights", only the kitchen headlights come on. It took us a while to realize that this was why things started at random. It only happens with a voice command via Siri, it doesn't matter if it's via HomePod or another device.

TL; DR: When I tell Siri to turn on the kitchen lights 100%, every HomeKit device in the system turns on.

Do you have a thought?
